Soft tissue fixation devices and methods
A suture button is provided that is adapted for soft tissue fixation. In one aspect, the button includes a textured bottom surface that allows gripping the soft tissue material and distributing the tension that holds the soft tissue to the bone thereby reducing the likelihood the soft tissue tearing.
1 . A suture button comprising a body having a planar top surface and a bottom surface, the top surface having an elevated bridge, the bottom surface having a textured surface, the body further having at least a first opening and at least a second opening, the at least first opening and the at least second opening being formed between the planar top surface of the body and the bottom surface of the body and allowing attachment of the suture button using a suture wire, the elevated bridge being positioned between the at least first opening and the at least second opening such that the entire region between the at least first opening and the at least second opening is elevated relative to the planar top surface and a remaining portion of the planar top surface surrounding the at least first opening and the at least second opening being level.
2 . The suture button of claim 1 , wherein the body defines exactly two openings, including the at least first opening and the at least second opening.
3 . The suture button of claim 1 , wherein the body comprises four openings, including the at least first opening and the at least second opening.
4 . The suture button of claim 1 , wherein the body has a circular shape.
5 . The suture button of claim 1 , wherein the elevated bridge includes an elongated dimension that runs perpendicular to an imaginary line connecting the center of each opening.
6 . The suture button of claim 5 , wherein the elevated bridge includes a rounded top portion.
7 . The suture button of claim 5 , wherein the elevated bridge includes elevated side portions on each end of the elongated dimension of the elevated bridge.
8 . The suture button of claim 1 , wherein the textured surface comprises a plurality of spikes.
9 . The suture button of claim 8 , wherein the plurality of spikes have a conical shape with either a rounded or sharp tip.
10 . The suture button of claim 8 , wherein the plurality of spikes are distributed evenly over the textured surface.
11 . A method for securing soft tissue to bone comprising the steps of:
securing a suture within the bone;
passing the suture through the soft material;
securing a suture button to the suture, wherein the suture button comprises a body having a planar top surface and a bottom surface, the top surface having an elevated bridge, the bottom surface having a textured surface, the body further having at least a first opening and at least a second opening, the at least first opening and the at least second opening being formed between the planar top surface of the body and the bottom surface of the body and allowing attachment of the suture button using a suture wire, the elevated bridge being positioned between the at least first opening and the at least second opening such that the entire region between the at least first opening and the at least second opening is elevated relative to the planar top surface and a remaining portion of the planar top surface surrounding the at least first opening and the at least second opening being level, wherein the securing of the suture compresses the textured surface against the soft tissue.
12 . The method of claim 11 , wherein the body defines exactly two openings, including the at least first opening and the at least second opening.
13 . The method of claim 11 , wherein the body comprises four openings, including the at least first opening and the at least second opening.
14 . The method of claim 11 , wherein the body has a circular shape.
15 . The method of claim 11 , wherein the elevated bridge includes an elongated dimension that runs perpendicular to an imaginary line connecting the center of each opening.
16 . The method of claim 15 , wherein the elevated bridge includes a rounded top portion.
17 . The method of claim 15 , wherein the elevated bridge includes elevated side portions on each end of the elongated dimension of the elevated bridge.
18 . The method of claim 11 , wherein the textured surface comprises a plurality of spikes.
19 . The method of claim 18 , wherein the plurality of spikes have a conical shape with either a rounded or sharp tip.
20 . The method of claim 11 , wherein the suture wire is secured to the bone using a knotless suture anchor, a screw-in suture anchor, or an interference fit suture anchor.
